VALVE-LIFTER.

iaoaaaa.

To all whom it may concern:

Be it known that I, FREDERICK C. FoLMAR, a citizen of the United States of America, and resident of Elm Grove, county of Ohio, and State of West Virginia, have invented certain new and useful Improvements in Valve-Lifters, of which the following is a specification.

This invention relates to valve lifters, and it has for its primary object to provide an improved form of tool for elevating the valve-seating springs of internal combustion engines.

A further object is to provide a tool of the character mentioned which is particularly eflicient for the purpose for which it is designed, which is extremely simple in construction and operation, and which may be conveniently handled.

With these and other objects in view, the invention resides in the features of construction which will hereinafter be fully described, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of the invention, showing the parts in spring-elevating position; Fig. 2 is a View partly in side elevation and partly in longitudinal section, showing the parts disposed in initial, or entering, position; Fig. 3 is a broken section on line 3-3, Fig. 2, showing portions of the tool members in top plan; and Fig. 4 is an enlarged transverse section of the extreme rear ends of the handle portions, showing the interlocking means.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several viewsl and 2 indicate generally the two members which compose the invention. The member 1 embodles a handle portion 1 which is preferably of semi-cylindrical form in cross-section, a fiat bifurcated head portion 3, and an intermediate arcuately curvedor bowed portion 4-; and the member 2 embodies ahandle portion 2 similar in form to that ofthe handle portion 1, a flat bifurcated head portion 5, .and an intermediate arcuately curved, or bowed portion 6. Said members are reversely disposed so that their fiat surfaces are opposed to each other. When in their normal relation shown in Fig. 1, said members have their said flat surfaces coinciding throughout the major part of the length of their curved or bowed portions and throughout the adjacent part of the handle portions.

Specification of Letters Patent.

Application filed March 17, 1916. Serial No. 84,786.

The member 2 has the front end of its bowed portion 6 curved somewhat more abruptly and prolonged to a greater extent than the member 1 so that the head 5 there of normally occupies a position wherein it Is elevated above the head 3 of member 1 the distance required to permit of ready introduction .and removal'of the usual pin or key 7 carried by the valve stem 8, as is clearly indicated in Fig. 1.

Fixed at an appropriate point in the bowed portion 6 of the member 2 is a pin or stud 9 which is movably disposed in a longitudinal slot 10 provided in the rear part of the bowed portion 4: of member 1, said stud serving to guide the movement of the member 2 in its movement from the lnitial, or entering position shown in Fig. 2 to the normal, or entered, position shown in Fig. l. A head 11 formed on said stud prevents said members from being disengaged, or disconnected. I

In practice, the member 2 is preliminarily withdrawn to the limit of the rearward movement permitted by. the cooperating slot 10 and stud 9 and the handle portion 2 thereof is elevated until'the points of the prongs 5 of its head 5 seat upon the prongs 3, as shown in Fig. 2. Then, with said parts occupying said positions, the head 3 of member 1 is placed in straddling relation to the valve-stem 8 at a point below the pin or key 7 and in a position wherein it seats upona stationary part, as 12, of the engine. In said position the points of said prongs will underlie the stem-encircling springseat 13. Then, downwardly.directed force applied to the handle portion 2 with a view to closing the same upon the handle portion 1 will cause the curved under face of the bowed portion (3 to slide forward upon the adjacent face of member 1, said adjacent face constituting a fulcrum. It will be noted that the fulcrum point is located substantially at the point of juncture of the handle portion 1 and the bowed portion 4:, and forward shifting movement of the member 2 is effected in a manner which may be termed automatic, due to the fact that the resultant forces acting upon the member 2 at opposite sides of the bowed portion 6 tend to cause the latter to seat within the bow of the corresponding portion l of member 1.

As the handle portion 2 closely approaches the handle portion 1, an inclined to abut, limiting forward movement.

surface 14 provided at the rear end of the latter is engaged by a link 15 which is pivotally mounted in the rear end of the former and deflects said link rearward. When said handle portions engage, the link gravitates to a position wherein the end of said member 1 is received therein, said link then servingto maintain said parts against chance relative movement. For preventing said link from becoming swung to a forward position wherein it will be prevented from engaging the inclined end 14, shoulders 16 are afforded by the provision of recesses in ,the end of the member 2, against which the upright portions of said link are adajclteid jacent to the rear ends of the members land 2, or at the part of the handle portions which is embraced by the hand of the user,

said members are so shaped that .an intervening space 17 is formed between the opposing faces'thereof, the purpose being to prevent said members from closing upon each other in such manner as to pinch the skin of the palm therebetween.

WVhat is claimed is 1. A tool of the character described, comprising two superposed members having a sliding connection, each of said members consisting of a head, a handle, and an intermediate downwardly bowed portion, the front end'of the bowed portion of the upper member being curved more abruptly and prolonged to a greater extent than the corresponding portion of the lower member so that, when said members are closed one upon the other with the bowed portions thereof interfitting, the head of the upper member will be elevated above the head of the lower member.

2. A tool of the character described, com-- thereof. 3. A tool of the character descrlbed, comprising two superposed members having faces designed to coincide throughout the major part of their length when the members occupy normal positions, each of said members consisting of a bifurcated head, a handle, and an intervening downwardly bowed portion, the curvature of the bowed portion of the upper member being more abrupt than that of the lower member and the head of said upper member being disposed at a relatively higher level than that of the lower member when the bowed portions assume interfitting relation, said lower member having a longitudinal slot in the rear part of the bowed portion thereof, and a stud carried by the upper member movably received in said slot.

4. A tool of the character described, comprising two superposed members having faces designed to coincide throughout the major part of their length when the members occupy normal positions, each of said members consisting of a head, a handle, and an intervening downwardly bowed portion, the curvature of the bowed portion of the upper member being more abrupt than that of the lower member and the head of said upper member being disposed at a relatively higher level than that of the lower member when the bowed portions assume interfitting relation, said lower member having a longitudinal slot in the rear part of the bowed portion thereof, and a downwardly projected stud fixed in the bowed portion of the upper member and niovably received within saidslot, said stud having a head for preventing disengagement of said members.

5. A tool of the character described, comprising. two superposed members having a connection which permits relative longitudinal sliding movement, each member consisting of a head, a handle and an intermediate downwardly bowed portion, the head of the upper member being disposed at a relatively higher level with respect to the handle than that of the lower member when the bowed portions assume interfitting relation, the upper member being adapted for assuming a position wherein the front part of its head seats upon the rear part of the head of the lower member and a substantially middle part of the bowed portion of the upper member rests upon the rear part of the bowed portion of the lower. member, and said upper member tending to automatically advance on said lower member under the resultant forces acting upon its head and its handle portion.

- tool of the character described, comprising two superposed members having a connection which permits relative longitudinal sliding movement, each member consisting of a head, a handle and an intermediate downwardly bowed portion, the head of the .upper member being disposed at a relatively higher level with respect to the handle than that of the lower member, said upper member being adapted to assume an inclined position when drawn rearward with respect to the lower member and to fulcrum upon the lower member at a point adjacent to the rear end of the bowed portion of the latter, so that the resultant forces acting on the head and the handle portion of the upper member act to advance the latter to a position wherein the bowed portions of said members interfit and the head of the upper member is elevated above the head of the lower member.

7. A tool of the character described, comprising two superposed members having a sliding connection, each of said members consisting of a head, a handle, and an intermediate downwardly bowed portion, the front end of the bowed portion of the upper member being curved more abruptly and prolonged to a greater extent than the corresponding portion of the lower member so that, when said members are closed one upon the other with the bowed portions thereof interfitting, the head of the upper member will be elevated above the head of the lower member, and means for maintaining the closed relation of said members.
